WebThe main theorem of Galois theory gives a correspondence between the intermediate fields of a finite extension L/K of fields on the one hand and the subgroups of the automorphism group G = Aut (L / K) on the other hand. In particular, this module will introduce the concepts of rings and fields including, for example, the notions of polynomial ...

WebAug 3, 2024 · This idea reflects the general concept of a group in mathematics, which is a collection of symmetries, whether they apply to a square or the roots of a polynomial. Galois groups were the first instances of the concept of a group, and Galois’ ideas blossomed into what today is a powerful, ubiquitous area of research called group theory. WebIntro Video; Week 1.
